T0 all whom it may concern ,A

Be it known that -LELZA H. REITER, a citizen of the United States,residing at Elgin, in the count' :of Kane, State of Illinois, haveinvente certain new and useful Improvements in'Flue-Cleaners; and I dohereby declaref the following to be a full, clear, and exact descriptionof theinvention, such as will enable others skilled in the art to whichit appertainsto make and use the' same. j

The present invention relates to certain novel and useful improvementsin a device for cleanin'g boiler iues and is in the nature of animprovement on the subject matter oi my patent forl Hue cleaner, Number966,051, dated- Aug. 2, '1910. Thisinvention has particular applicationto a structure adapted to be connected to the doors of return flueboilers whereby thecleaning operation may be thoroughly and rapidlyaccomplished without the necessity of opening the doors. y

Still a further object of my invention is to simplify and improve theconstruction and increase the efici vncyl and utility of devices of thischaracter; j

I also aim `to provide an attachment whereby each individual flue oftheboiler may be reachedl from-a plurality of points,

in the present instance two in number, so that the cleaning operationmay be speedily and conveniently accomplished.

It is also my purpose to provide a cleaning device wherein the elementsconstituting the same may be adjusted to such positions' as thccircumstances maydemand, and furthermore I propose tov provide 'a devicewhich/will embodyr the desired features of simplicity and durabilitycoupled with cheapness of cost in manufacture, sale and installation.

With the above recited objects and others of a similar nature in viewmyinvention consists in the construction, combination and arrangement ofparts set forth in and falling within the scope of the appended claim.

In the accompanying drawing like characters of reference indicate likeparts in all the views, and,

Figure 1 is a sectional side elevation of the front portion .of a boilerand illustrating the application of my invention. Fig. 2 is a `frontelevation of the device detached. Fig.'

3 is a cross sectional view taken on the line vided,

' 3 3 of Fig. 2. i 4 is a sectionalviewlon' the line 4 4 of Fig. 2.

Referring A indicates convenwhich lis the front thereof, 2 2 a frontdoor and 3 the tubes or iues;

Each of thedoors is provided with an adjustable /supporting attachmentfor thc blower .0r cleaning device proper, and as these attachments aresimilar in 'construction 'a description of one will suicefor all. Eachdoor is provided approximately centrally with an aperture 4 through'which is designed to project the tubular member of the blower, said'opening being preferably provided with a pivote-d closure plate 5.

The numeral 6- indicatesas an' entirety a U-shaped frame having anotched or serrated Vcross bar 7, whileth parallel arms 8-8 of saidframe are provided at their free ends with bolt holes 9 designed toreceive the Patented sept. 29,- 1914... 1

now to the accompanying draw-,- ving in detail, the letter l tio-nallyaboiler of any approved type of* shank portions 10." of theangular-hingedbolts 11, the shanks 12 of said lbolts project- `ingthrough the adjacent portions of the wall ofthe iue cap door. and areheld in place thereto by the nuts 13, while the nuts 14 are employedtopivo-tally hold the frame in position on the Shanks 10. The notchedbar l`7 of each frame is propreferablycentrally thereof, with anaperture 15 for. the passage of the threaded shank 16 of the curvedorsegmental bar 17. The shank is provided with' the adjustable nuts18-18 b means of which the-length of the bar maylie adjusted to slightlyraise or lower the inner` end of they blow' pipe to Vstrike the tube orliuc yat the proper point.

Furthermore the. aperture 15 issllghtly elongated and enough larger thanthe threaded shank 1.6 to permit of the latter hav,-

Ing sufficient lost motion to play .loosely in such aperture Vtherebyallowing the weight of the bar 17'to cause it to drag on the lower edgewall of the slot 19 formed in the doorV and through which the barprojects. It will be noted that the segmental bar is provided at itsunder edge with a plurality of teeth or serrations 2O designed to engagewiththe lower edge wall of the aperture 19 so that the bar may beadjusted to any required eX- tent within the range of the teeth-ornotches,

thus -correspondingly adjusting the U- shaped frame 6. Furthermore, itwill be noted 'thatfwhi-le thel segmental toothed or notched bar iscarried by the U-shaped instances, with which I am acquainted itframeit, at theSametime performs the ventionally illustrated, comprisesthe blow pipe'21`to which is connected one end of the hose 22, theopposite end of the hose being attached as at 23 to the steam pipe 24. i

From the above description taken in connection with the accompanyingdrawing the construction and y operation of my improved device will bereadily apparent. ln operation the doors being closed,.the segmental baris firstadjusted to locate the U-shaped cross bar in proper po-sition tohold the blow pipe pointed towardI the Vrow of l iiues 'in which it isdesired to operateand the pipe is then passed through the aperture 4inthe closed door and'the inner end of the pipe inserted into one of thelues. t The steam is then. admitted through'the blower, passing throughthe tube from the front tothe rear, and thoroughly cleaning the soot orother products `of combustion without exposing the boiler head anddrawing the cold air in with the steam. 'Ihus while blowing one tube,the draft is on all'the othertubes and the hot gases are drawn in withI,the steam practically super-heating the latter and eliminating themoisture therefrom. will be further notedl from the resent drafar-` i'ngand description that the b ower may. be,l

operated at either door opposite the center of the tube area thusblowing half the'tubes' from the center of each door. Itvwill be furtherseen that as the cleaner is operatedwhile the doors are closed, thebankv of tubes may be cleaned withoutchecking `the draft or interruptingthe service of `the boiler. In Ipractice the bars 7 areprovidedjwithnotches corresponding to the nim'ibervv of tubes in eachhorizontal row of the tube bank so that when the device/ is in operationthe shifting of the blower tube 'from one notch of the bar 7 to the nextnotch also shifts the inner end ofthe blower from one tube to theadjacent tube'of therow-` I am' aware of the fact that hitherto it hasbeen proposed to support ay Hue blower pipe on the furnace in positionto afford the end of the pipe access to the flue. But in all such hasbeen necessary to form a relatively large special opening in the wall ofthe boiler setting, usually the rear wall, and install in said opening aspecially constructed frame which carries the supporting mechanism ofthe blower pipe yor liue cleaner proper. Such a construction isillustrated in my earlier patent hereinbefore mentioned.V In the presentinstance however, by forming a special opening in the flue door at thefront of the boiler I am enabled to blow the tubes from the front or therear while the doors are closed so that there. isno interference withthe draft or service of the boiler. Furthermore I obviate the expenseand disadvantage of .breaking the wall of the boiler settingandinstalling the frame and other parts therein.

While I have herein shown and described one particular embodiment of myinvention, I wish it to be understood that I do not yconfine myself toall of the precise details of construction herein set forth by way ofillustration, as modification and variation may be made without departinfrom the spirit of the invention or eXcee ing the scope of the appendedclaim.

What I claim is:

The combination with a flue door formed -with an opening therein for thepassage of a ktube cleaning device and a second opening for the-passageyof a segmental rack bar, of a tubecleaning device, a support for saiddevce comprising a Ufshaped frame, angular bolts pivotally connectingthe leg portions of the lframe. to the door and at opposite sides of theiirst mentioned opening, so that the frame may swin freely on theyangular bolts, a segmental'rac bar adapted to adjustyably engage withthe wall of the second opening in the-flue door, said bar having a shankprojecting through a relatively large aperture inthe cross bar of theU-shaped frame so that said shank may have a limited amount of play inthe aperture, and means 'for adju'stably securing the' shank portion ofthe` rack bar to the cross bar of the frame.

In testimony whereof, I ailix my signature, in presence of twowltnesses.
